It can very quickly test the cold cranking amps of your current automobile battery along with validating the alternator charging functionality. It has been very helpful for troubleshooting no start electrical conditions. I checked the voltage displayed on this tester against my calibrated Fluke DVM and it was 100% accurate. This tester is easy enough to use that I could hand it to my kid and they'd be able to check their car's battery and charging system without any instructions. Just need to follow the clear prompts on the menus. The zip up soft case this tester comes with is handy to protect it in a trunk and the case has space to store the product manual if you need it. I paid ~$60 USD for this tester, so it wasn't the cheapest, but I gladly pay more for accuracy and complete testing capabilities over the less expensive automotive testers on desertcart. Review: Very impressed. This unit is awesome and is 100% accurate. Highly recommend. - I spent days searching for a good unit. This has great reviews and is sold online a lot. I decided to buy it. I'm so very happy that I did. This unit is awesome and is 100% accurate. I even tested this against other devices and this is spot on. I bought a brand new odessey performance battery for $400 and I bought as well to test. The battery says 765 CCA. This device says 770 CCA. That is awesome. I love the color screen and how big it is. So easy to use. So many features on this little device. It also measures votage accurately. Great functionality and battery life is very long. So very easy to read everything. I highly recommend this. ## Features - 🏆 All-in-One Battery Tester: The FOXWELL BT301 is an upgraded version of the trusted BT100, designed for car enthusiasts, DIYers, and professionals.
